Description

TECHNICAL FIELD

[0001] The utility model relates to a safe detection device of fire facility flame detector. BACKGROUND

[0002] In the field of building fire facilities, for the detection of building fire facility flame detector, the infrared light source or ultraviolet light source or the combination method of the two is often used to simulate the flame. But the simulation light source has the limitation of not being able to completely simulate the flame effect, which often causes the flame detector not to react to the simulation light source, so that the detection result cannot be determined; if the open fire ignition detection method is used, it is easy to cause safety problems on site. Therefore, a safe detection device of building fire facility flame detector needs to be developed. SUMMARY

[0003] In order to solve the problems encountered in the detection of the flame detector in the past, the application provides a safe detection device of fire facility flame detector, characterized in that: a single-end opening quartz glass cover 1 is provided with a fire starting device 2, the fire starting device 2 is provided with one or more than one burner 3, the fire starting device 2 is located on the body of the non-combustible rubber body 4, the outer periphery of the non-combustible rubber body 4 is sealingly connected with the inner periphery of the opening end of the quartz glass cover 1, the non-combustible rubber body 4 is provided with an adjustable check valve 5, the air inlet of the adjustable check valve 5 leads to the inside of the quartz glass cover 1, the air outlet of the adjustable check valve 5 leads to the outside space, the non-combustible rubber body 4 is provided with a first air outlet 6 and a first air inlet 7, one end of the first air outlet 6 is connected with a first valve 8, the other end of the first valve 8 leads to the outside space, one end of the first air inlet 7 is connected with a second valve 9, the other end of the second valve 9 is connected with a second air outlet 11 of a blower 10.

[0004] The quartz glass cover 1 can transmit the infrared and ultraviolet rays in the flame, and does not affect the detection of the flame detector on the flame in the quartz glass cover 1. The air convection between the quartz glass cover 1 and the outside space is to prevent the flame in the quartz glass cover 1 from causing the combustion of combustible gas or combustible material in the outside space. The number of burners 3 used is related to the detection distance, and appropriate setting can realize the response of the flame detector to the flame in the quartz glass cover 1. In the time period from the start of normal detection of the flame detector to the normal response of the flame detector, the amount of oxygen in the quartz glass cover 1 should be able to ensure that the flame burning in the quartz glass cover 1 is always burning. The size of the space in the quartz glass cover 1 can be set accordingly. The pressure relief function of the adjustable check valve 5 is to prevent the pressure in the quartz glass cover 1 from being too high during the combustion process. When the gas pressure in the transparent quartz glass cover 1 is higher than the atmospheric pressure of the outside space by a certain value, the adjustable check valve 5 releases pressure to the outside space and resets,

[0005] The first valve 8 and the second valve 9 serve two functions: In operating mode one, both valves 8 and 9 are closed. The flame of the burner 3 inside the quartz glass cover 1 can only be maintained for a certain period of time. The flame burning time must be greater than the time it takes for the flame detector to detect the flame and then respond normally. If the flame detector responds, it is normal; otherwise, it is unqualified. After detection, fresh air is introduced through the first valve 8 and the second valve 9 to replace the exhaust gas after combustion inside the quartz glass cover 1. In operating mode two, both valves 8 and 9 are open. The second air inlet 12 of the blower is connected to the external space. During combustion, introducing an appropriate amount of fresh air through the blower can achieve a longer period of continuous flame combustion.

[0006] The aforementioned safety detection device for a fire protection facility flame detector can be improved as follows: the second air inlet 12 of the blower 10 is connected to the first air outlet 14 of the one-way valve 13, the first air inlet 15 of the one-way valve 13 is connected to the second air outlet 17 of an inflatable sealing airbag 16, the second air inlet 18 of the inflatable sealing airbag 16 is connected to the third air outlet 20 of the third valve 19, the third air inlet 21 of the third valve 19 is connected to the external space, and a combustible gas detector 22 is provided inside the inflatable sealing airbag 16.

[0007] The function of the blower 10 is to supply gas from the inflatable sealing bladder 16. When the third valve 19 is opened, the interior of the inflatable sealing bladder 16 communicates with the external space.

[0008] The function of the one-way valve 13 is to ensure that the air in the expandable sealing airbag 16 can only flow from the expandable sealing airbag 16 to the second air inlet 12 of the blower 10, and cannot flow in the opposite direction.

[0009] The function of the expandable sealing airbag 16 is to store a certain amount of air to adapt to use in conjunction with the one-way valve 13, the combustible gas detector 22 and the third valve 19 in an environment where combustible gases may be present.

[0010] The function of the third valve 19 is to connect or isolate the air inside the expandable sealing airbag 16 from the outside space. When there is no combustible gas in the working environment, the third valve 19 can be kept open, the blower 10 can run continuously, and the flame of the burner 3 inside the quartz glass cover 1 can burn for a longer period of time.

[0011] The function of the combustible gas detector 22 is that when this detection device is used in an environment where combustible gases may be present, the air that enters the space inside the quartz glass cover 1 to provide oxygen for combustion must first be detected by the combustible gas detector 22, and only when it is safe to do so can the blower 10 draw it into the quartz glass cover 1.

[0012] The inflatable sealing airbag 16 is in an automatically inflating state under natural conditions. This utility model relates to a safety detection device for flame detectors in fire protection facilities. Its features include: a ignition device 2 installed inside a single-ended open quartz glass cover 1; the ignition device 2 has one or more flame nozzles 3; the ignition device 2 is mounted on a non-combustible rubber body 4; the outer periphery of the non-combustible rubber body 4 is sealed to the inner periphery of the open end of the quartz glass cover 1; the non-combustible rubber body 4 is equipped with an adjustable one-way valve 5; the air inlet of the adjustable one-way valve 5 leads to the inside of the quartz glass cover 1, and the air outlet of the adjustable one-way valve 5 leads to the outside space; the non-combustible rubber body 4 has a first air outlet 6 and a first air inlet 7; the first air outlet 6 is connected to one end of a first valve 8, and the other end of the first valve 8 leads to the outside space; the first air inlet 7 is connected to one end of a second valve 9, and the other end of the second valve 9 is connected to the second air outlet 11 of a blower 10. This utility model, by using an isolated real flame as the detection source for the flame detector, is effective, accurate, and safe. The third air intake 21 draws in air from the outside space.

[0013] In operating mode two, both valves 8 and 9 are open. When the expandable sealing bladder 16 is in its natural expansion state, it inflates. Once fully inflated, valve 19 is closed, isolating the air inside the bladder from the outside space. The air inside the bladder is detected by the combustible gas detector 22. If the detector does not alarm, blower 10 is started to deliver the safety air from the bladder 16 into the quartz glass cover 1. During this process, the bladder slowly deflates and releases air. Once deflating is complete, the flame in the quartz glass cover 1 extinguishes. This completes one test. For subsequent use, valve 19 is opened again, allowing the bladder to automatically inflate and connect to the outside space. Once fully inflated, valve 19 is closed. The combustible gas detector 22 checks the air inside the bladder. If no alarm is triggered, the blower can be started for the next ignition test.

[0014] This invention uses an isolated real flame as the detection source for the flame detector, thus ensuring effectiveness, accuracy, and safety. Attached image description:

[0018] Example 1:

[0019] See Figure 2 , Figure 3 This application provides a safety detection device for a flame detector in a fire protection facility. Its features include: a ignition device 2 housed within a single-ended open quartz glass cover 1; the ignition device 2 has three burners 3; the ignition device 2 is mounted on a non-combustible rubber body 4; the ignition device 2 has its own power supply and control system; it uses liquid fuel typically found in lighters; and it has an overall explosion-proof structure. The ignition device 2 is ignited electronically via remote control. The outer periphery of the non-combustible rubber body 4 is sealed to the inner periphery of the open end of the quartz glass cover 1. The non-combustible rubber body 4 is equipped with an adjustable one-way valve 5. The air inlet of the adjustable one-way valve 5 leads into the quartz glass cover 1, and the air outlet of the adjustable one-way valve 5 leads to the external space. The non-combustible rubber body 4 has a first air outlet 6 and a first air inlet 7. The first air outlet 6 is connected to one end of a first valve 8, and the other end of the first valve 8 leads to the external space. The first air inlet 7 is connected to one end of a second valve 9, and the other end of the second valve 9 is connected to the second air outlet 11 of a blower 10. When combustion is maintained solely by the oxygen present in the air within the quartz glass enclosure 1 (in operating mode one, both valves 8 and 9 are closed), the ignition device 2 will automatically extinguish itself 10 seconds after ignition due to oxygen deficiency. To extend the combustion time, operating mode two is used, where both valves 8 and 9 are opened, and the blower 10 is activated to introduce fresh air to maintain combustion. The blower 10 is an adjustable speed type. After each test, the interior of the quartz glass enclosure 1 should be purged with fresh air using the blower.

[0020] The quartz glass cover 1 allows infrared and ultraviolet rays from the flame to pass through, without affecting the flame detector's detection of the flame inside. Isolating the quartz glass cover 1 from air convection in the outside space prevents the flame inside the quartz glass cover 1 from igniting flammable gases or materials in the outside space. Three burners are used, arranged horizontally facing the flame detector. During the period from the start of normal detection to the normal response of the flame detector, the oxygen level inside the quartz glass cover 1 is sufficient to ensure continuous combustion of the flame within it. This allows the size of the space inside the quartz glass cover 1 to be set. The adjustable one-way valve 5 relieves pressure to prevent excessive pressure in the quartz glass cover 1 during combustion. When the gas pressure inside the transparent quartz glass cover 1 exceeds a certain value of atmospheric pressure in the outside space, the adjustable one-way valve 5 releases pressure to the outside space and resets.

[0021] Example 2:

[0022] See Figure 1 When there is a possibility of flammable gas at the testing site, the following method is adopted: Figure 1In this method, based on the application of Embodiment 1, the second air inlet 12 of the blower 10 is connected to the first air outlet 14 of the one-way valve 13, the first air inlet 15 of the one-way valve 13 is connected to the second air outlet 17 of an inflatable sealing airbag 16, the second air inlet 18 of the inflatable sealing airbag 16 is connected to the third air outlet 20 of the third valve 19, the third air inlet 21 of the third valve 19 is connected to the external space, and a combustible gas detector 22 is provided inside the inflatable sealing airbag 16.

[0023] The function of blower 10 is to supply gas from inflatable sealing bladder 16. When the third valve 19 is opened, the interior of inflatable sealing bladder 16 communicates with the external space. Blower 10 has its own power supply and control system, and features an overall explosion-proof structure.

[0024] The function of the one-way valve 13 is to ensure that the air in the expandable sealing airbag 16 can only flow from the expandable sealing airbag 16 to the second air inlet 12 of the blower 10, and cannot flow in the opposite direction.

[0025] The function of the expandable sealing airbag 16 is to store a certain amount of air to adapt to use in conjunction with the one-way valve 13, the combustible gas detector 22 and the third valve 19 in an environment where combustible gases may be present.

[0026] The function of the third valve 19 is to connect or isolate the air inside the expandable sealing airbag 16 from the outside space. When there is no combustible gas in the working environment, the third valve 19 can be kept open, the blower 10 can run continuously, and the flame of the burner 3 inside the quartz glass cover 1 can burn for a longer period of time.

[0027] The function of the combustible gas detector 22 is that when this detection device is used in an environment where combustible gases may be present, the air that enters the space inside the quartz glass cover 1 to provide oxygen for combustion must first be detected by the combustible gas detector 22, and only when it is safe to do so can the blower 10 send it into the quartz glass cover 1.

[0028] The inflatable sealing airbag 16 is in an automatically inflating state under natural conditions, and draws in air from the outside space through the third air inlet 21 of the third valve 19.

[0029] When the expandable sealing airbag 16 is in its natural expansion state, it inflates. Once fully inflated, the third valve 19 is closed, cutting off the air inside the airbag 16 from the outside space. The air inside the airbag 16 is detected by the combustible gas detector 22. If the detector does not alarm, the first valve 8 and the second valve 9 are opened, the blower 10 is started, and its speed is adjusted appropriately to send the safety air from the airbag 16 into the quartz glass cover 1, maintaining the flame of the burner 3. During this process, the airbag 16 slowly deflates and releases air. Once the deflation is complete, the flame in the quartz glass cover 1 will extinguish. This completes one test. For subsequent use, the third valve 19 is opened again, allowing the airbag 16 to automatically inflate and connect to the outside space. The blower 10 is then started to purge the inside of the quartz glass cover 1. After the airbag 16 is fully inflated, the third valve 19 is closed. The combustible gas detector 22 checks the air inside the expandable sealed airbag 16. If there is no alarm, the blower can be started for the next ignition test. The maximum internal volume of the expandable sealed airbag 16 can store enough air for each normal test.

[0030] The rest is the same as in Example 1.
